1. Field of the Invention
The invention relates to a snowboard binding comprising a stable base plate made of solid or rigid materials. Such a base plate is provided for being mounted on a snowboard. Its top side is formed to serve as a stand-on plane for supporting the sole of a snowboarding boot, with a calf support substantially aligned perpendicularly to the stand-on plane of the base plate for supporting the back of the lower leg of the snowboarder. Furthermore, it comprises at least one coupling element for connecting the snowboarding boot—detachably, if necessary—with the base plate.
2. The Prior Art
Numerous snowboard bindings are known that comprise a base plate, via which such a binding system can be mounted on a snowboard. The shape and size of such a base plate approximately conforms to the sole of a boot intended for snowboarding. As a rule, the base plate is dimensioned slightly shorter than the length of the sole of the snowboarding boot, which can be fixed and detached by means of the snowboard binding as required. Furthermore, it is known to form extensions in the longitudinal marginal areas of the base plate, such extensions protruding upwards perpendicularly to the stand-on plane of the base plate. Said extensions, which are relevant to the rigidity of the base plate, are molded onto the latter, preferably forming one single piece with the base plate, and, furthermore, may sere as mounting extensions for holding a support bracket in the shape of a “U”, viewed from the top. Such a U-shaped support bracket is intended for surrounding the heel part of the snowboarding boot, whereby such a U-shaped support bracket can be supported in such a way that it is individually adjustable and fixable vis-à-vis the base plate in the longitudinal direction of the binding for adapting it to different boot sizes. For said purpose, provision is made for a number of breakthroughs or oblong holes in the edge-side extensions of the base plate, or in the two legs of the support bracket, such passages or holes being spaced from each other and intended for receiving fastening screws, as it is shown, for example in EP 1 127 592 A1. Furthermore, the known snowboard bindings comprise a so-called calf support, via which the user of the snowboard binding is supported in the rearward direction. Such a calf support may be supported directly on the extensions, and can be swiveled to an extent limited by stop means around a pivotal axis extending transversely to the longitudinal axis of the binding. Alternatively, such a rotational support can be formed directly on the U-shaped support bracket. The limitation for stopping the calf support in the rearward direction is preferably effected by a stop element on the calf support. Such snowboard bindings are usually equipped with belt arrangements and/or automatic coupling devices for forming so-called “step-in” bindings. Such known binding systems have the drawback that their adaptation to the individual requirements of the snowboard rider is possible only to a relatively limited extent.
The present invention is based on the problem of providing a snowboard binding that permits superior adaptation to the individual preferences, as well as superior adaptation to the physical conditions of different snowboarders.
Said problem of the invention is resolved by a snowboard binding in connection with which the base plate is formed by at least two base plate components, whereby the front and the rear base plate components each form a support for the front and rear parts of the snowboarding boot, and the alignment and/or orientation between the front and rear base plate components can be changed and fixed by the snowboarder as needed, with the calf support being mounted on the hear base plate component.
One of the advantages of the snowboard binding as defined by the invention lies in that its base plate can be individually adapted in the best possible way to the preferences and conditions of the user. In particular, it is possible in a simple manner to adapt the base plate of the snowboard binding to the given boot size or length of the sole and/or shape of the snowboarding boot. Owing to such adaptability of the base plate to the size or length, it is possible to increase or optimize the comfort of the snowboarder, on the one hand, and to upgrade the performance achievable with such a snowboard binding on the other. In addition to such benefits for the user of the snowboard binding, various positive effects are gained for a dealer or lessor of such a snowboard binding as well. In particular, the variety of sizes or types of snowboard bindings that have to be offered to all kinds of different persons interested in snowboarding can be reduced because the snowboard binding as defined by the invention can be adapted to different preferences and many conditions of use in a simple manner. But positive effects benefit also the manufacturer of the snowboard binding as defined by the invention equipped with the special base plate. In particular, by producing just one base plate it is nonetheless possible to offer a certain variety of different types of snowboard bindings, so that the production costs are reduced. Especially the number of cost-intensive injection molds required for their production can be kept low. An important benefit can be seen also in that the snowboard binding or its base plate as defined by the invention can be easily adapted in a simple way to left-side or right-side use. It is particularly possible with only one design of the base plate to at least approximately adapt two structurally identical snowboard bindings to the shape of the sole of the left and the shape of the sole of the right snowboarding boot. Furthermore, in a surprising and unforeseeable manner, the snowboard binding as defined by the invention permits enhanced control or steering of a snowboard as well. It is particularly possible by means of the snowboard binding as defined by the invention to raise the individual steerability or rate of reaction of a snowboard if the base plate and the calf support are optimally adapted to the individual snowboarder. This is achieved primarily if the calf support can be set to the position of optimal transmission of force from the leg of the user and the snowboard. In particular, the controlling forces exerted by the user can be transmitted to the snowboard in a superior manner because the calf support, which is supposed to further transmit the controlling forces exerted by the foot of the user, taking into account the given position of the leg, can be adjusted as optimally as possible. Twisted positions interfering with the locking of force between the calf support and the calf or leg of the snwoboarder can be avoided in a simple way with the snowboard binding as defined by the invention. In particular, owing to the theoretically relatively extensive swiveling range of the calf support within a relatively large range of the angle of rotation, what is achievable without problems is that the calf or the snowboarding boot will act on the supporting surface of the calf support over as large a surface area as possible. Therefore, the snowboard binding as defined by the invention permits in a simple way easy adjustability of the calf support with respect to its angular position around an axis extending about vertically in relation to the base plate, as well as also adaptation of the base plate to different sizes and shapes of snowboarding boots.
Advantageous is also a further development of the snowboard binding, where a rotational support is provided between the front and rear base plate components, said support forming a pivotal axis aligned substantially perpendicularly to the stand-on plane, because such a design provides a one-piece, multi-component base plate that can be easily mounted on a snowboard in a simple manner. In addition, such a rotational support, which couples the two base plate components with each other, provides a usefully limited relative adjustment between the front base plate component and the rear base plate component.
An embodiment of the snowboard binding, where the pivotal axis of the rotational support can be positioned and fixed within the stand-on plane with limited variability, is advantageous as well because the curvature and longitudinal expanse of the base plate comprised of the two base plate components can be individually changed in this way, or adapted to the given requirements in the best possible way.
A particularly simple and quick change of the adjustments is made possible owing to the fact that a single central adjusting and locking device is formed for the rotational support.
An embodiment of the snowboard binding, where the front and rear base plate components overlap one another in their end sections facing each other, is beneficial as well because a base plate having as much stability and dimensional rigidity as possible is obtained in this way.
With the embodiment of the snowboard binding, where the rear base plate component is supported on the front base plate component in a manner transmitting the load, the relative adjustability of the rear base plate component versus the front base plate component remains independent of the surface condition of a snowboard, so that the intended adjustability of the rear base plate component is always assured.
The embodiment of the snowboard, where a circular suppressing disk is formed that bridges both the front and the rear base plate components, is advantageous in that its permits endless or unlimited pivoting of the base plate around the circular suppressing disk
The further development of the snowboard binding, where the suppressing disk positively connects the front base plate component with the rear base plate component, forming the rotational support, offers the advantage that a defined relative position is maintained between the two base plate components, because the front base plate component and the rear base plate component are kept positioned via the suppressing disk in the vertical direction relative to the pivotal axis of the rotational support.
An embodiment of the snowboard binding, where at least one oblong breakthrough for a fastening means is formed in the suppressing disk for mounting it on a snowboard in variable positions, is advantageous as well because the snowboard binding or base plate can be individually positioned in this manner also transversely to the longitudinal direction of the snowboard.
The embodiment of the snowboard binding, in connection with which at least one oblong breakthrough is formed in each of the front and rear base plate components for passing through fastening screws for securing the two base plate components on a snowboard, permits each base plate component to pivot individually in relation to the snowboard, on the one hand, as well as individual alignment of the angular position of the entire snowboard binding vis-à-vis the snowboard on the other.
The embodiment of the snowboard binding, where the breakthroughs are circular with respect to the stand-on plane, pivoting of the base plate components around a defined axis is achieved, and interfering deviations of the base plate components in the radial direction relative to the pivotal axis are prevented from occurring.
Owing to the fact that the angle between the center axis of the front base plate component and the center axis of the rear base plate component can be adjusted and fixed within a maximum range of from 150° to 180°, preferably from 165° to 180°, the two base plate components can be relatively adjusted, starting from a stretched position to a curved position, whereby high stability of the base plate is achieved because adequately high dimensions of material thickness can be used in the transitional zone between the front base plate component and the rear base plate component.
The embodiment of the snowboard binding, in connection with which the angle between the center axis of the front base plate component and the center axis of the rear base plate component can be adjusted and fixed within a maximum range of from 150° to 210°, preferably from 165° to 195°, offers the advantage that viewed from the top, it is possible with only one base plate to adjust an alignment of the latter either cranked to the left or cranked to the right, so that the snowboard binding as defined by the invention can be adapted to both the shape of the left and the shape of the right snowboarding boot. At the same time, such a design permits an optimal alignment of the calf support, which in turn permits an ideal transmission of controlling or steering forces to the snowboard.
In the embodiment of the snowboard binding, in which at least one adjusting and locking device for activating and deactivating a clamping connection is provided between the front and the rear base plate components, an infinitely variable adjustment of the relative positions between the base plate components is made possible. In addition, a structurally simple adjusting and locking device is made available at the same time, which in turn permits the snowboard binding to be structured at favorable cost.
In the embodiment of the snowboard binding, where an adjusting and locking device is provided for activating and deactivating a positive connection between the front and the rear base plate components, whichever relative positions between the base plate components are deemed preferable can be fixed with high stability, and undesirable adjustment movements between the base plate components are safely suppressed even if force is introduced in the form of pulses.
Canting or oblique positions between the respective top sides or stand-on planes of the base plate components can be set because the pivotal axis of the rotational support is inclined versus the stand-on plane. The angle of force introduction or direction of transmission of the controlling forces can be additionally changed or adapted in this manner.
Due to the fact that at least one of the base plate components is provided with a wedge-like shape, the inclination of the calf support can be advantageously changed in a simple way by changing the positions of the two base plate components in relation to one another. In addition, it is possible to change the ratio of the support pressure of the snowboarding boot between the front and the rear base plate components.
A safe and stable connection is created between the two base plate components on account of the fact that at least one support plane between the front base plate component an the rear base plate components is inclined with respect to the stand-on plane for the snowboarding boot, which, in addition, permits the angle of inclination to be changed in a simple manner.
In the embodiment of the snowboard binding, in which a adjustably supported wedge element is arranged between the rear base plate component and the front base plate component for supporting the load, it is advantageous that the inclination of the calf support can be adjusted independently of its angular position, or irrespectively of the angular position of the rear base plate component. In particular, the inclination of the calf support can be maintained unchanged if the angular position of the calf support is changed around a vertical axis in accordance with the preferences of the snowboarder. Analogously, the inclination of the calf support can be changed via the adjustably supported wedge element without altering the angular position of the calf support.
The embodiment of the snowboard binding, in which the wedge element is supported in a linearly adjustable manner and its relative position can be individually changed by the snowboarder, it is beneficial that the angle of inclination of the calf support can be changed in a simple way as well.
The embodiment of the snowboard binding, where the wedge element is rotationally supported, pivoting around an axis extending substantially perpendicularly relative to the stand-on plane, permits quick changing of the angle of inclination of the calf support depending on the given angle of rotation of the wedge element relative to the rear base plate component.
Owing to the design of the snowboard binding, in connection with which the rear base plate component holds the calf support by means of at least one pivotal joint forming a pivotal axis extending transversely to the longitudinal axis of the binding and substantially parallel to the stand-on plane, the calf support is capable of assuming a position in which it is pivoted downwards, which is particularly space-saving when the binding is not in use.
Owing to the embodiment of the snowboard binding, in which the pivotal joint or base plate is forming a device for limiting the angle of rotation between the calf support and the rear base plate component in the rearward direction, the intensity or direction of the introduction of controlling forces into the snowboard can be additionally changed or adapted.
With the embodiment of the snowboard binding, in which the rear base plate component is forming or supporting a U- or bracket-shaped support element with respect to the stand-on plane, and said pivotal joint is holding the calf support within a limited range of rotation of the latter on an axis of rotation extending transversely to the longitudinal axis of the binding and substantially parallel to the stand-on plane, and/or at least the rear section of the U- or bracket-shaped support element is disposed behind the rear-most edge of the rear base plate component and above the stand-on plane, and/or the lower-most end section of the calf support is disposed behind the rear-most edge of the rear base plate component and at a distance above the stand-on plane, what is accomplished is that any premature contact with the surface of the snowboarding course is avoided even when the snowboard binding is in steeply slanted positions.
The assembly of the snowboard binding or of the base plate components is simplified in that face ends of the front base plate component and the rear base plate component facing each other are butt-jointed.
By virtue of the fact that at least one edge-shaped “clear” position or intermediate space is formed between face ends of the front and rear base plate components facing one another for the purpose of relative adjustability between the front and the rear base plate components, it is possible to ensure an adequate change in the orientation between the base plate components, or change in the alignment between the two base plate components.
The embodiment of the snowboard binding, in which ends of the front base plate component and ends of the rear base plate component overlapping one another are curved or provided with a semicircular shape, is advantageous as well in that the resulting transition between the two base plate components has as few gaps as possible between said components, with the latter being in any angular position in relation to each other.
An embodiment of the snowboard binding, in which the front base plate component and the rear base plate component overlap one another substantially without any steps, i.e. smoothly, and/or the suppressing disk adjoins the front and the rear base plate components substantially steplessly as well, forming a substantially ridgeless, smooth connection, is advantageous as well in that in this way, no annoying pressure points will act on the foot of the snowboarder as the snowboarding boot is supporting itself in a load-transmitting manner on the base plate.
A further development of the snowboard binding, in connection with which the suppressing disk is provided on its underside with at least one extension with a wedge-shaped cross section, such an extension extending circularly or in a circular arc-shaped form around a center point of the suppressing disk, is advantageous in that it permits a reliable incremental or infinitely variable adjustment of the alignment of the base plate components versus the central suppressing disk.
The embodiment of the snowboard binding, in connection with which at least one groove-like recess, the latter being positively engageable with the at least one wedge-shaped extension, is formed in the front base plate as well as also in the rear base plate component, permits changing the curvature of the base plate as well as also the overall length of the base plate in a simple manner.
The embodiment of the snowboard binding, in which the spacing between the front and the rear base plate components can be changed and fixed, is advantageous as well in that different sizes of snowboarding boots can be optimally supported or received in this way with only one type of base plate.
Furthermore, the embodiment of the snowboard binding, in connection with which the width of the overlap between the front and rear base plate components is variable, permits the overall length of the base plate to be easily changed in a simple way.
The embodiment of the snowboard binding, in which at least one breakthrough or passage for receiving a screw is formed in a section of the overlap between the front and the rear base plate components, whereby the diameter of the screw shaft is smaller than the dimension of the at least one breakthrough or passage extending in the direction of the longitudinal axis of the binding, permits a quick change in the overall length of the base plate, so that the latter can be optimally adapted to the length of the sole of the snowboarding boot, or to the width of the snowboard being used.
Owing to the embodiment of the snowboard binding, in which several positive connection means in the form of elevations or recesses are formed in a section of overlap between the front and the rear base plate components, such connection means corresponding and being selectively engageable with each other, and spaced from each other in the direction of the longitudinal axis of the binding, the total length of the base plate can be incrementally changed, whereby the adjusted total length is reliably fixed.
A safe and highly stable fixation of the adjustments selected for setting the total length of the base plate is assured by the embodiment of the snowboard binding in which the width of the overlap between the suppressing disk and at least one of the two base plate components can be changed and fixed as selected by the snowboarder by means of a plurality of positive connecting means in the form of extensions and recesses that correspond and are selectively engageable with each other.
However, especially advantageous is also the snowboard binding in connection with which a lateral limiting bridge, the latter being connected with and fixed on the front base plate component, and extending slidingly movably or relatively adjustably over the closest section of the rear base plate component, because any deviating or lift-off movements of the rear base plate component comprising the calf support, are counteracted in this way. In particular, the stability of the divided, multi-component base plate can be increased in this manner, and the thickness of the material of the base plate components can be selected relatively low without impairing the stability.
The embodiment of the snowboard binding, in which a lateral limiting bridge, which is connected with and fixed on the rear base plate component, is extending slidingly movably or relatively adjustably over the closest section of the front base plate component, is beneficial in that the front base plate component can be firmly pressed against the top side of the snowboard as the snowboard binding is being mounted on the latter.
Finally, the embodiment of the snowboard binding, in which limiting bridges arranged on opposite lateral edge sections of the front base plate component extend diverging from each other in the direction of the front base plate component, starting from the end section facing the rear base plate component, is advantageous in that the snowboarding boot can be received in this way in the snowboard binding with the least amount of play possible, because the heel part of the boot is comparatively narrower than the part of the boot disposed closest to the toes or balls of the toes. Moreover, in association with the changeability of the contour of the base plate, it is possible to achieve optimal adaptation to the snowboarding boot, so that the latter can be fixed in the snowboard binding free of play. Owing to such an arrangement with the least amount of play possible, the steerability of the snowboard equipped with the snowboard binding is increased because any delay in the transmission or transfer of force can be eliminated to the greatest possible extent.
The invention is explained in greater detail in the following with the help of the exemplified embodiments show in the drawings, in which:
It is noted here by way of introduction that in the different exemplified embodiments described herein, identical components are provided with identical reference numbers or identical component designations, whereby the disclosures contained throughout the present specification may be applied in the same sense to identical components with the same reference numbers or component designations. Furthermore, data relating to positions selected in the specification such as, e.g. “top”, “bottom”, “lateral” etc. relate to the figure directly described and shown, and have to be applied in the same sense to any new position where a position has changed. Moreover, individual features or combinations of features of the different exemplified embodiments shown and described herein per se may represent independent inventive solutions or solutions as defined by the invention.
In the following description, terms such as “rearwards” or “rear” relate to the heel section or the area of the snowboard binding 1 disposed closest to the calf of the leg. On the other hand, terms such as “frontal” or “front” relate to the toes or sections of the snowboard binding 1 disposed closest to the balls of the toes.
When the snowboard is in use, the sole of the snowboarding boot, which is not shown for the sake of superior clarity, is supported on a substantially plane stand-on surface 4 of the base plate 3 of the snowboard binding 1 in a way transmitting the load or force. Said surface 4 may slightly ascend in the face-side end areas, if need be. The base plate 3 is conceived in this connection for safely mounting it on the snowboard 3 in such a way that it cannot be torn off. In particular, the base plate 3 is provided with such stability that forces such as, e.g. steering forces occurring between the foot of the snowboarder and the snowboard 2 are safely absorbed and transmitted. The supporting or statically relevant elements of the base plate 3 are therefore made of solid or rigid materials such as, e.g. hard plastic and/or light metal.
As known per se, the base plate 3 may also comprise on its top side, or as part of the stand-on plane 4 at least one slip-proof or soft-elastic support cushioning for the sole of the snowboarding boot, as indicated by broken lines. Such a support cushioning is connected with the top side of the base plate 3, for example by gluing or screwing it to the latter. If necessary, the at least one support cushioning is partly received or inserted in a corresponding deepening on the top side of the base plate 3, as it indicated by broken lines.
Furthermore, a calf support 5 is formed in connection with the snowboard binding 1 shown, said calf support being substantially aligned perpendicularly to the stand-on plane 4 for the snowboarding boot. Such a calf support 5, which is frequently referred to as a so-called “highback”, serves for supporting the lower part of the back of the leg of the snowboarder for efficiently transmitting controlling or steering forces between the foot of the snowboarder and the snowboard 2. In particular, the calf support 5 projects upwards from the rearward area of the base plate 3 like a pole or wall.
The maximum angle of gradient or inclination 6 between a substantially vertically aligned support surface 7 for the rear section of the boot of the snowboarder, and the substantially horizontally extending stand-on plane 4 on the base plate 3 is either prefixed or adaptable to the individual requirements of the snowboarder. For such adaptation, the calf support is pivot-mounted and capable of swiveling to a limited extent around at least one pivotal axle 9 extending substantially transversely to the longitudinal axis 8 of the binding, and substantially parallel to the stand-on plane 4. In practical applications, the maximum angle of inclination 6 of the calf support 5, which is limited by a stop element, amounts to about 110°. The maximum angle of inclination 6 between the stand-on surface 4 and the calf support 5 is usually individually fixable at a value in the range of 75° and 100°. For storing or transporting the snowboard binding 1 in a space-saving manner, it is possible also to pivot the calf support 5 in the direction of the base plate 3, or to fold it down, as it is known per se, so that the calf support 5 will then be substantially aligned parallel to the base plate 3.
For individually adjusting the maximum angle of inclination 6, provision may be made for a manually adjustable stop element 10 that determines the limitation of the maximum angle of inclination 6 of the calf support 5 in the rearward direction. The swiveling range of the calf support 5 in the rearward direction is limited in this connection depending on the position or alignment of said stop element 10. However, for limiting the maximum angle of inclination 6 for the calf support 5 it is possible also to employ other designs known from the prior art.
Furthermore, the snowboard binding 1 comprises at least one coupling element 11, 12, for detachably—if need be—connecting particularly a snowboarding boot with the snowboard binding 1 or its base plate 3. The at least one coupling element 11, 12 may be formed in this connection by at least one belt arrangement 13. Particularly a belt arrangement comprising a belt on the instep side and a belt on the toe side can be used in order to realize a safe and adequately play-free connection of the foot of the snowboarder with the snowboard 2. Alternatively to a belt-like coupling element 11, 12, or in combination with the belt arrangement 13, it is possible also to provide an automated coupling device in order to provide a connection between the snowboarding boot and the snowboard 2 that can be activated and deactivated as required and as comfortably as possible. In particular, the snowboard binding 1 may be a so-called belt binding or a so-called “step-in” binding.
So as to be able to better adapt the snowboard binding 1 to the physiological conditions or individual requirements of the snowboarder, the base plate 3 is designed to comprise at least two components, so that said base plate 3 is comprised of at least one front base plate component 14 and at least one rear base plate component 15. In particular, the base plate 3 is assembled from at least two base plate components 14 and 15, which are lined up one after the other, or from at least two of such base plate components that are at least partly arranged one on top of the other, and adjustable relative to each other as needed, whereby the size of the stand-on plane 4 and/or a defined contour of the base plate 3 is obtained or can be individually adjusted. Therefore, the base plate 3 of the snowboard binding 1 comprised of at least two components can be individually changed and fixed with respect to its stand-on surface area for the snowboarding boot and/or with respect to its contour.
The base plate 3 is consequently formed by at least the two base plate components 14 and 15, whereby the front and the rear base plate components 14 and 15, respectively, each form a support for the front and rear sections of the sole of the snowboarding boot.
In the embodiment shown, the base plate 3 is divided in its center section, whereby the front base plate component 14 and the rear base plate component 15 partly merge into one another. In particular, the front and rear base plate components 14 and 15, respectively, overlap each other in their end sections associated with each other.
The coupling element 12 or the front belt arrangement 13 is preferably mounted on the front base plate component 14, and the rear coupling element 11 or the rear belt arrangement 13 is preferably connected with the rear base plate component 15.
It is important that with the help of the two-component embodiment of the base plate 3 of the snowboard binding 1, the alignment and/or orientation between the front and rear base plate components 14 and 15, respectively, can be changed by the snowboarder preferred, and fixed in the desired relative position. In this connection, the calf support 5 is supported on the rear base plate component 15 and connected for moving jointly with the latter.
In particular, the base plate 3 comprising at least two components permits that at least the alignment or orientation between the front base plate component 14 and the rear base plate component 15 usefully can be changed to a limited extent by the user or dealer selling the snowboard binding 1. This permits easy adaptation to the individual needs or preferences of the snowboarder, and the performance achievable with the snowboard binding 1 or snowboard 2 can be optimized. On the other hand, the snowboarder's comfort in using this equipment can be raised owing to the individual adaptability of the base plate 3 to the shape of the boot or given boot dimensions or contours of the sole of the boot.
Adjustability of the orientation between the front and rear base plate component 14 and 15, respectively, means that the angle 16 between the center axis 17 of the front base plate component 14, and the enter axis 18 of the rear base plate component 15 can be changed as required or preferred. Based on the starting position shown by way of example in
Alternatively, a bidirectional change in the angle 16 is possible as well, based on the long-stretched starting position shown by way of example. Therefore, with the preferred bidirectional variability of the angle 16, starting from a value of 180°, it is possible to adjust and fix that said angle 16 between the center axis 17 of the front base plate component 14 and the center axis 18 of the rear base plate component 15 within a maximum range of from 150° to 210°, usefully within a range of 165° and 195°. In other words, based on the long-stretched position, the angle 16 can be changed to at least one other enlarged or reduced position with an obtuse angle 16.
A relative position between the front base plate component 14 and the rear base plate component 15 is illustrated in
It is useful if a rotational support 19 is provided between the front base plate component 144 and the rear base plate component 15 as shown in
In the present schematized embodiment, the pivotal axis 20 of the rotational support 19 is extending between the front and rear base plate components 14 and 15, respectively, exactly perpendicularly to the stand-on plane 4 for the snowboarding boot, or exactly perpendicularly to the lower side of the base plate 3.
In the embodiment shown in
Furthermore, it is useful if the ends of the first or front base plate component 14 and the second or rear base plate component 15 overlapping one another have a curved or about semicircular shape, as it is shown most clearly in the representation according to
Instead of using a single-tooth or leaf-like tooth connection, it is possible also to provide a multi-tooth system, whereby a multitude of the extensions 23 are formed on each base plate component 14, 15, which, in conjunction with corresponding indentations or slots results in a positive, flexible connection or overlap between the end sections of the base plate components 14 and 15 facing each other.
The at least one flattening on each of the ends of the base plate components 14 and 15 facing each other, results in this connection in a substantially stepless, smooth transition, so that a uniform base plate 3 is formed that appears to consist of only one single piece. Alternatively, it is possible also that the extension 23 of the one base plate component 14 or 15 engages a corresponding slot-like recess 24 in the other base plate component 15 or 14, forming the rotational support accordingly.
In its center section, i.e. where the base plate components 14 and 15 overlap one another, the base plate 3 can be joined with the snowboard 2 in a tear-off proof manner. For this purpose, at least one fastening means 25 is formed, via which the snowboard binding 1 or base plate 3 is connectable with the snowboard 2. Such a fastening means 25 is preferably formed by a screw 26. In the advantageous embodiment shown, a total of four screws 26 are provided for safely connecting the base plate 3 or two base plate components 14 and 15 with the snowboard 2 in a tear-off proof manner. However, it is possible also to provide for only two or three screws 26 for securing the snowboard binding 1 on the snowboard 2.
In the embodiment according to
The center points of the screws 26 are disposed in this connection in the corner points of an imaginary square, or in the corner points of an equally sided triangle. The spacing between the corner points of such a square or triangle amounts to approximately 4 cm. The width 22 of the base plate 3 in the center section comes to from 100 mm to 140 mm, so that the diameter of the semicircular extension 23 or semicircular recess 24 has a value in the range of from 100 mm to 140 mm as well. The circular arc-shaped circumference of the extension 23 or the peripheral edge of the circular arc-shaped recess 24 is preferably extending over more than 180°, e.g. over about 200°, so that the angle 16 between the front and rear base plate components 14 and 15, respectively, can be enlarged and also reduced.
Such an embodiment offers the special advantage that it is possible by means of the fastening means 25, or the screws 26 for securing the snowboard binding 1 of the snowboard 2, to create at the same time an adjusting and locking device 30 that permits an individual adjustment and fixation of the desired orientation or alignment of the base plate components 14 and 15, as well as also changing of the angular position of the base plate 3 or snowboard binding 1 vis-a-vis the longitudinal axis of the snowboard 2. Therefore, the adjusting and locking device 30 described above for the rotational support 19 permits changing and fixing the relative angular position between the base plate components 14 and 15, on the one hand, and also changing of the angular position of the entire base plate 3 or entire snowboard binding 1 relative to the longitudinal axis of the snowboard 2 on the other. Thus the rotational support 19 between the front base plate component 14 and the rear base plate component 15 is also a rotational support for the entire snowboard binding 1 or the entire base plate 3. The individual components or the total structure are pivoted in this connection around the common pivotal axis 20.
In the present embodiment, the adjusting and locking device 30 is formed by a structurally simple clamping connection between the overlapping sections of the base plate components 14 and 15, in conjunction with the top side of the snowboard 2, whereby said clamping connection can be activated or deactivated as needed. In particular, by loosening the respective screws 26 it is possible to easily change the relative positions of the base plate components 14 and 15 versus the snowboard 2, whereas by tightening the screws 26 or fastening means 25, the respective relative adjustability is cancelled. This assures safe and stable fixation of the desired relative positions versus the snowboard 2. For increasing the holding or clamping force of the clamping device or the locking force of the adjusting and locking device 30, it is possible also to make provision for means for increasing the friction between the respective surfaces abutting one another. Alternatively to or in combination with such a measure, it is possible also to make provision for positive connections or tooth systems for fixing the base plate components 14 and 15 vis-à-vis the top side of the snowboard 2, so that such fixation will safely withstand high forces. In other words, at least one adjusting and locking device 30 is formed that is designed for activating and deactivating a rigid connection between the front and rear base plate components 14 and 15, respectively. Such an adjusting and locking device 30 also permits the angular position of the entire snowboard binding 1 versus the snowboard 2 to be changed, particularly versus the longitudinal axis of the latter.
In order to achieve safe holding of the snowboarding boot on the base plate 3, the lateral limiting bridges 31 and 32 are formed preferably on the front and rear base plate components 14 and 15, respectively, said limiting bridges being arranged near the lateral edges of the base plate components 14 and 15. Said limiting bridges 31, 32, which are protruding substantially vertically from the stand-on plane 4, mainly prevent the snowboarding boot to slip off sideways versus the base plate 3. In addition, the limiting bridges 31, 32 opposing one another in the transverse direction relative to the longitudinal axis of the binding, are frequently used for securing the coupling elements 11, 12—particularly of the type of the belt arrangements 13—on the base plate 3 in a tear-off proof manner. For this purpose, provision is made for the screw-like or positively acting fastening means 33, which ensure particularly a rotationally movable and tear-off proof connection between the belt components of the belt arrangement 13 and the base plate 3, such a connection having limited mobility.
In the present embodiment, the front base plate component 14 is extending over a clearly longer longitudinal section of the base plate 3 than the comparatively shorter structured rear base plate component 15. In particular, the longitudinal expanse of the rear base plate component 15 amounts to about one fourth of the longitudinal expanse of the entire base plate 3 with respect to the longitudinal axis 8 of the binding.
The rear base plate component 15 again carries the calf support 5, i.e., the latter is mounted on said rear base plate component 15. The rear base plate component 15 and thus also the calf support 5 are changeable as needed within preset limits with respect to their orientation and alignment versus the front base plate component 14, and their desired adjustment is fixable, which is obvious if
In the present embodiment as well, the rear base plate component 15 rests at least partly on the front base plate component 14, which is shown best by the sectional representation according to
The screw-and-nut arrangement 35 penetrates the two base plate components 14, 15 in their flat sections overlapping or covering one another. At least one of the two breakthroughs 36, 37 in the base plate components 14, 15 for receiving the screw-and-nut arrangement 35 has a dimension greater than the largest diameter or cross section of the screw-and-nut arrangement 35 within said breakthroughs 36, 37. What is achieved in this way is that the rear base plate component 15 with the screw of the screw-and-nut arrangement 35 inserted therein, is relatively adjustable versus said comparatively large breakthrough 37, and the clamping connection 34 can be activated to assume the relative position desired between the base plate components 14 and 15. The limits of such relative adjustablity are determined in this connection by the size and form ratio between the at least one breakthrough 36, 37 and the connecting screw of the screw-and-nut arrangement 35.
The nut of the screw-and-nut arrangement 35 may be formed in this connection by a so-called flanged or cap nut for building up a stable and safe clamping connection 34. Alternatively, it is possible also to use shims or washers and the like in order to ensure safe clamping between the two base plate components 14 and 15.
The important feature is that the alignment and orientation of the rear base plate component 15, or of the calf support 5 coupled therewith, can be changed as required versus the front base plate component 14 owing to the formation of at least one breakthrough 37 that is enlarged with respect to the screw diameter. The enlarged breakthrough 37, which is preferably formed in the front base plate component 14, may have a semicircular, circular, crescent-like, rectangular or square shape, or it may be formed by a plurality of slots extending at an angle relative to one another. The breakthrough 37 in the front base plate component 14 is preferably covered by the rear base plate component 15 disposed on top of it, which is shown best in the sectional representation according to
Therefore, the rear and front base plate component 15 and 14, respectively, overlap each other in the present embodiment as well, whereby the clamping connection 34, which can be activated and deactivated as required, is provided within said section of overlap, permitting fixation of the desired relative positions between the front and the rear base plate components 14 and 15, respectively.
The clamping connection 34 with the comparatively large breakthrough 37 for receiving the screw of the screw-and-nut arrangement 35 permits changing the alignment of the angle between the base plate components 14 and 15, on the one hand, and changing of the relative position between the two base plate components 14 and 15 in the direction of the longitudinal axis 8 of the binding, on the other. According to the embodiment shown, it is possible as well to change the relative position of the pivotal axis 20 for the rotational support 19 vis-à-vis at least one base plate component 14, 15, since the cross sectional dimensions of the breakthrough 37 are larger than those of the screw extending through the breakthrough 37.
Alignment between the base plate component 14 and 15 particularly is to be understood to mean a lateral offset between the center axes 17 and 18 of the front and rear base plate components 14 and 15, respectively, and/or a variation in the spacing between the two base plate components 14 and 15. It is particularly possible with the embodiment according to
Based on the starting position shown, any individual change in the lateral and/or longitudinal offset and/or orientation or alignment of the angle between the center axes 16 and 17 of the base plate components 14 and 15, respectively, is made possible in a simple manner for the snowboarder, lessor or seller of the snowboard binding 1 by means of the adjusting and locking device 30.
In the embodiment shown, the rear base plate component 15 is forming a U-shaped or bracket-like support element 39, the latter being mounted on the rear base plate component 15. Said support element 39 is U-shaped or has the contours of a bracket with respect to the stand-on plane 4. Said stable support element 39, which is capable of withstanding high support forces, holds or carries the calf support 5. In particular, the calf support 5 is flexibly connected with the support element 39 via the pivotal joint 40 forming the pivotal axle 40 already described above, whereby the swiveling movement of the calf support 5 is limited in the rearward direction by at least one stop means in the form of a device 41 limiting the angle of traverse. Said limiting device 41 comprises the stop element 10 already described above, which can be variably positioned and fixed in its vertical position versus the calf support 5. In particular, the maximum angle of inclination 6 of the calf support 5 is limited in that once a defined angle of inclination 6 has been reached, the stop element 10 comes to rest against the support element 39, particularly against its top edge, which prevents the calf support 5 from any further pivoting motion.
The rear section of the U-shaped or bracket-like support element 39 is preferably disposed at a distance 42 of 5 to 10 cm behind the rear-most edge of the rear base plate component 15. In addition, the rear section of the U- or bracket-shaped support element 39 is disposed above the stand-on plane 4. In particular, the lower-most end section of the calf support 5 or support element 39 is positioned at a distance 42 behind the rear-most edge of the rear base plate component 15, and at a distance 43 above the stand-on plane 4. What is achieved in this way is that it is possible with the snowboard binding 1 or snowboard 2 to assume relatively steep positions versus the ground, particularly vis-a-vis the surface of the snowboarding course, without parts of the snowboarding boot or snowboard binding 1 brushing against the surface of the course.
In the embodiment shown, a circular breakthrough 44 is formed in about the center area of the base plate 3, in which a corresponding circular suppressing disk 45 is inserted in order to solidly connect the base plate 3 or snowboard binding 1 with the snowboard 2 in different positions of the angle of rotation. The circular breakthrough 44 and the suppressing disk 45 have the corresponding extensions 46, 47, respectively, which assure that the suppressing disk 45 mounted on a snowboard 2 will solidly fix the associated base plate 3 on the snowboard, safely preventing it from lifting or tearing off. The suppressing disk 45 is mounted on the snowboard 2 via at least one fastening means 25, particularly by a plurality of the screws 26. The suppressing disk 45, with the at least one extension 47, extends over the at least one extension 46 in the peripheral area of the breakthrough 44. When the suppressing disk 45 is loosened versus the snowboard 2, rotation of the base plate 3 or snowboard binding 1 is made possible in the manner known per se in view of the longitudinal or transverse axis of the snowboard 2. In association with the circular breakthrough 44 in the base plate 3, the suppressing disk 45 thus forms a rotational support 48 for the base plate 3 or the snowboard binding 1. Said rotational support 48 defines an axis 49 extending perpendicularly to the top side of the snowboard 2. In the present embodiment, the rotational support 48 with the vertical axis 49 is spaced versus the pivotal axis 20 of the rotational support 19 between the front base plate component 14 and the rear base plate component 15 in the direction of the longitudinal axis 8 of the binding. In other words, this means that in the present embodiment, a substantially vertically extending pivotal axis is formed between the front and rear base plate components 14 and 15, respectively, and, in addition, a further axis 49 is separately formed, the latter being associated with the base plate 3 and the suppressing disk 47 on the one hand. On the other hand, in the embodiment according to
In the present embodiment according to
It is known per se that the base plate 3 may comprise a plate-like attachment part 51 in at least one end section on the face side. Such an attachment part 51, which is often referred to also as the “gas pedal” of the snowboard binding 1, has a slip-inhibiting surface and/or an inclined, ascending top side 52. In particular, said attachment part 51 may comprise the stand-on cushioning described above. The purpose of the friction-increasing surface or slanted, ascending top side 52 is to enhance the transmission of force between the snowboarding boot or its arched sole, and the snowboard binding 1 or snowboard 2. Such an attachment part 51, which is known per se and may be formed in the front end section or also in the rear end section of the base plate 3, may possibly also serve as an element for changing the length of the base plate 3, because it is optionally possible to connect the attachment part 51 with the base plate 3 in a number of possible positions distributed in the direction of the longitudinal axis 8 of the binding. It is possible in this way to adapt the snowboard binding 1 to different boot sizes with only one single type of base plate 3 comprising an attachment part 51 variably positioned in the longitudinal direction. Thus only one base plate 3 is required in order to accommodate different boot sizes. The immovable connection of the attachment part 51 with the base plate 3 in the set positions is realized with a screw 53 that can be anchored in one of several predefined screw holes, or in an oblong hole in the base plate 3. Said wedge-shaped, slippage-inhibiting attachment part 51, which is known per se, exclusively serves for telescopically changing the longitudinal expanse of the base plate 3.
The base plate 3 according to
The rear limitation bridges 31 are formed in this connection by the legs of the U-shaped support element 39.
In the present embodiment, the base plate 3 is a two-component plate as well, whereby the plane of separation is positioned in about the longitudinal center of the base plate 3, said plane of separation extending substantially transversely to the longitudinal axis 8 of the binding.
The two base plate components 14 and 15 jointly forming the base plate 3 for safely supporting the snowboarding boot, are butt-jointed in line, i.e., in the present embodiment, the front and rear base plate components 14 and 15, respectively, do not overlap each other. In particular, the face ends of the front and rear base plate components 14 and 15, respectively, facing one another are disposed next to each other. In the present exemplified embodiment, the base plate components 14 and 15 abut each other substantially gap-free in a center point 50. Alternatively, however, it is possible also to form a through-extending gap between the base plate components 14 and 15, since the latter are kept in their respective nominal positions by means of the suppressing disk 45, as explained in detail below.
In the present embodiment of the snowboard binding 1, viewed from the top, the front base plate component 14 and the rear base plate component 15 are bridged by a circular suppressing disk 45, and said two base plate components 14 and 15 are connected and maintained in their nominal positions in that way. The suppressing disk 45 bridges only a part section of the two face ends of the front and rear base plate components 14 and 15 facing one another, as it is clearly visible in the representations according to
It is particularly advantageous if the suppressing disk 45 positively connects the front base plate component 14 with the rear base plate component 15, and at the same time forms the rotational support 19 between the front and rear base plate components 14 and 15, as well as also the rotational support 48 between the base plate 3 and the snowboard 2 assembled in this manner.
A possible positive connection between the suppressing disk 45 and the two base plate components 14 and 15, such connection forming at the same time the rotational supports 19 and 48, respectively, is shown in
The respective extension 56 on the bottom side of the suppressing disk 45 is preferably extending in the form of a circle or circular arc around the center point 50 of the circular suppressing disk 45. As an alternative, a circular arrangement of bar-like or pin-shaped extensions 56 on the bottom side of the suppressing disk 45 is possible as well. In the assembled state, said at least one extension 56 on the bottom side of the suppressing disk 45 engages at least one corresponding recess 57 in the two base plate components 14 and 15.
It is advantageous if the extension 56 has a wedge-shaped cross section, i.e. if it has the two slanted surfaces 58, 59 extending at an angle relative to one another, whereby the angle enclosed between said slanted surfaces 58, 59 amounts to between 30° and 150°, preferably to about 90°. The recess 57 in the two based plate components 14, 15 corresponding therewith is a groove-like deepening so as to produce a positive connection or rotational support 19 between the two base plate components 14, 15 via the suppressing disk 45, as best shown in
Furthermore, it is useful if, with respect to the top side, the suppressing disk 45 substantially steplessly adjoins the front and rear base plate components 14 and 15, resulting in a substantially smooth transitional connection. In particular, the suppressing disk 45 is arranged sunk or deepened in the two base plate components 14 and 15 in order to form a stand-on plane 4 that is as plane-faced and smooth as possible. Especially any central elevation or center ascent in the base plate 3 is avoided due to the deepened arrangement of the suppressing disk 45.
The suppressing disk 45 may be formed by high-strength plastics, particularly from glass fiber-reinforced plastics, or from metal, particularly a light metal such as, e.g. aluminum. Low wall thickness values and small component dimensions are achievable particularly if the suppressing disk 56 is made of aluminum or a metal alloy, whereby high holding or clamping forces are nonetheless achievable for the two base plate components 14 and 15 via such a suppressing disk 45.
It is especially shown in
Furthermore, it is clearly shown in
It is shown, furthermore, that at least one oblong breakthrough 27 for a fastening means 25, particularly for a screw 26 is formed in the suppressing disk 45 for mounting it on a snowboard 2 in variable positions. It was found to be advantageous if the suppressing disk 45 has three or four of such breakthroughs 27 for mounting screws.
Both the front and rear base plate components 14 and 15, respectively, each comprise at least one recess 61, 62, respectively, disposed in the face ends facing one another. Said recesses 61 and 62 assure that each base plate component 14 and 15 is relatively movable versus the stationary fastening screws 26 anchored in the snowboard 2 after the fastening screws have been loosened, and the clamping force acting between the suppressing disk 45 and the base plate components 14 and 15 thus has been cancelled. The dimensions of the recesses 61 and 62 have to be selected larger than the diameter of the screws 26.
It is useful if a lateral limitation bridge connected fixed to the rear base plate component 15 is slidingly movably or relatively adjustably extending over a section of the front base plate component 14 disposed closest to it. In this way, the base plate components 14 and 15 are fixed in a stable and deviation-resistant manner. What is achieved in particular is that in the presence of high vertical forces acting on the front base plate component 14, the latter will remain in position on the snowboard 2 in a relatively stable and substantially unyielding way. Such an additional supporting or holding effect is achieved owing to the lateral limitation bridges 31 and 32 extending between the front and rear base plate components 14 and 15, respectively.
Alternatively or in combination with the above measures, it is possible also that a limiting bridge 32 connected with and fixed on the front base plate component 14, or molded onto said front component, forming one piece with the latter, is extending starting from the front base plate component 14 in the direction of the rear base plate component 15, and supported on the latter with sliding mobility, as shown in
Furthermore, as shown most clearly in
The embodiment according to
The connection or coupling between the rear and front base plate components 15 and 14, respectively, is formed in this conjunction by a bolt or screw connection forming also the pivotal axis 20 of the rotational support 19.
It is important in this connection that the pivotal axis 20 of the rotational support 19 is extending inclined versus the stand-on plane 4 of the rear base plate component 15, or vis-à-vis the stand-on plane 4 of the entire base plate 3. Furthermore, at least one of the two base plate components 14, 15 is wedge-shaped. In the present exemplified embodiment, both base plate components 14 and 15 are wedge-shaped in at least part sections, as shown most clearly in
It is advantageous if the connecting means, particularly the screw-and-nut arrangement 35 between the rear and front base plate components 15 and 14, respectively, is aligned inclined in relation to the stand-on plane 4. It is particularly beneficial if the axis of the screw-and-nut arrangement 35, which coincides with the pivotal axis 20, is extending perpendicularly to the support plane 63, 64. A simple connection can be realized in this manner between the base plate components 14 and 15 without having to make provision for complex shapes. Particularly the use of spherical segment-shaped screw heads and ball sockets for receiving the screw head is avoided by such measures.
The screw-and-nut arrangement 35 represents in this connection also the adjusting and locking device 30 which, through application of clamping forces, ensures safe fixing of the adjusted position of the angle of rotation of the calf support 5 or the rear base plate component 15.
It is advantageous if provision is made in the either horizontal or inclined support plane 63 and/or 64 between the base plate components 14 and 15, for a means increasing the friction, and/or for a tooth system 65 for safely fixing the adjusted positions of the angle of rotation. In particular, by providing for means for increasing the friction, or a tooth system 65 between the support surfaces or the support planes 63, 64, it is possible to create a coupling between the base plate components 14 and 15 that is secured against rotation to a high degree when the adjusting and locking device 30, the latter being formed by the screw-and-nut arrangement 35 or a lever arrangement, is activated or screwed tight with adequate torque.
According to the embodiment shown in
In particular, the overlap width 68, 69 between the suppressing disk 45 and at least one the base plate components 14, 15 can be changed and fixed by the snowboarder as needed by means of the positive connection means 70 in the form of the extensions 56 and recesses 57, said means corresponding with each other and being selectively engageable.
It can be understood best in association with
For increasing the stability and cohesion between the two base plate components 14 and 15, it may be useful if the rear base plate component 15 extends under the front base plate component 14, as indicated in
For increasing the stability of the base plate 3 assembled from the base plate components 14 and 15, it is possible also to connect the base plate components 14 and 15 and/or the lateral limitation bridges 31 and 32, respectively, with each other in the manner of a telescope or hinge. Such a telescopic or hinged connection permits changing the orientation and/or alignment between the base plate components 14 and 15 with increased overall stability as well.
